After viewing the YouTube app that came preinstalled in my Android TV Box (Android 7.1.2 OS) for about 6 hours without any problems, now when I launch the YouTube app I get "The installation package was not found." This happened by itself without me fiddling around with the TV Box or its settings. I would turn on the TV Box, launch the app, watch it for awhile, then turn off the box. The box is new and I have only used it 3 times before this problem surfaced. Any suggestions for solving this problem? Thanks.
